In accordance with the relevant provisions of the "Science and Technology Evaluation Measures" of the Ministry of Science and Technology, in line with the principles of science, independence, objectivity and impartiality, the third-party professional scientific and technological achievements evaluation institution Zhongke Hechuang (Beijing) Science and Technology Achievement Evaluation Center (hereinafter referred to as "Zhongkehe" In the recent days, he organized industry experts from Henan University of Technology, Zhengzhou University, North China Institute of Water Conservancy and Hydropower, Zhongyuan Institute of Technology, Zhengzhou Abrasives Grinding Research Institute and other units to Zhongnan Diamond Co., Ltd. (hereinafter referred to as “Zhongnan Diamondâ€). The Kela class IIa diamond R&D project carried out scientific and technological achievements evaluation. The members of the expert group believe that the project is devoted to the research and industrialization of the caramel type IIa diamond synthesis technology, the development of a special catalyst, the design of a multi-layered infiltration assembly structure, the improvement of the precision and stability of the synthetic control equipment, and the improvement of carbon. In the source treatment and synthesis process, IIa type diamonds with a particle size of 4 to 7 mm and a single crystal weight of 0.6 to 1.2 carats are synthesized under high temperature and high pressure conditions, and the yield is over 90%, realizing the industrial production of type IIa diamonds. Tested by the Jewelry Testing Center of China University of Geosciences, the product is processed into a jewelry drill, the color is equivalent to the DE grade of natural diamond, and the clarity is equivalent to the VS-SI grade of natural diamond. The crystal form of the product is relatively complete, the cutting processing loss is low, and the ground diamond reaches the overall effect of natural diamond. At the same time, the project has received 3 invention patents and 3 authorized utility model patents. The expert group unanimously believes that the project has made breakthroughs in mass production of large-size products, and the overall process technology has reached the domestic leading level. 
After a comprehensive review by the expert group, it was unanimously agreed that the Zhongnan Diamond “Clar Grade IIa Diamond R&D†project passed the evaluation of scientific and technological achievements. Zhongnan Diamond is the first enterprise in China to mass produce 4-7mm high-quality synthetic diamonds; the research success and industrialization of the project can effectively replace imports, greatly reduce over-exploitation of natural scarce diamond resources, and better meet the people's increasing The need for a better life of growth has an important impact on the company's future and the field of decoration.The Solar Panel adopts the advanced lamination technology which combines special glass with multiple thin films to make the solar cells reach the best performance and longer lifetime. With the corrosion resistance special aluminum frame, the panel could be pretty sturdy and be used for outdoors without any concerns. The long lasting surface glass makes sure the panel's outdoor lifetime will be more than 15 years.
